Title: Vehicle gap detector
Inventor: KATSUNO TOSHIYASU
IPC: G06T1/00
Filed: 1992-09-25
Abstract: PURPOSE:To enhance the detection response of the vehicle gap especially at night by rapidly detecting the vehicle gap in the title detector using a CCD sensor. CONSTITUTION:The image signal from CCD sensors 10,12 are stored in either one of an RAM 1 (18a) and an RAM 2 (18b) through decimation circuits 14 and A/D 16. Each of the RAMs has capacity storing the image data of a CCD 1 frame and a CPU 22 stores the image data in the RAMs 1, 2 alternately. The RAMs 1, 2 are alternately accessed by ASIC 20 to execute correlation operation using the stored image data. Since the image data of the next frame is stored in the RAM 2 during a period when correlation operation is executed using the image data stored in the RAM 1, even when the charge time of CCD is increased at night, correlation operation can be immediately executed.

Title: Inter-device phase difference absorption circuit
Inventor: EKOSHI HIROYA
IPC: H04L7/00
Filed: 1994-10-21
Abstract: PURPOSE: To absorb a phase difference without the need of the elastic memory of large capacity by obtaining a clock signal faster than a first clock signal by twice the transmission delay time among devices and processing a data signal in synchronizing with the clock signal. CONSTITUTION: A master clock is supplied to one input of PLO 10 in a rack A. The output line 15 of PLO 10 reciprocates between the rack A and a rack B and it is connected to the other input of PLO 10. The output of PLO 10, which reaches the rack B, is inputted to a signal processing circuit 18 and the output of the circuit 18 is transmitted to the rack A. When transmission delay time between the racks A and B is set to be T1, the output of PLO 10 is supplied to one input of PLO 10 by delaying it by 2T1 hours, and the phase of two input in PLO 10 are matched. Thus, the clock signal whose phase is made faster than that of the master clock in the rack A by 2T1 is outputted from PLO 10.

IPC: G06T5/00
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To replace a combination of primary color image signals with a medium image signal by utilizing a nonlinear function in a reflectance coordinate. SOLUTION: A relative reflectance of a colorant is represented on a print sheet on X, Y coordinates in Figure. A relationship between a reflectance and a density is expressed by a nonlinear function. Thus, is the case of converting the density into the reflectance, R(D)=1-10-D, 0<=D<Dmax , R(Dmax )=1. R is an absorption factor and then (1-R) depicts a reflectance. In the simple case of f1(x)=f2(x)=f3(x)=f4(x)=x, signals for three colors of colorant are attained; one is a primary color colorant, the other is a hi-fi colorant, the rest is k. A signal on a basis of re-converted reflectance is used later to control a digital printer.

Abstract: PROBLEM TO BE SOLVED: To provide a scratch and blur-writing brush font forming device in which a writing brush font is inputted and is converted and outputted to a writing brush font provided with scratch or blur. SOLUTION: The writing brush font is inputted and is converted into a binary picture format and a character skeleton from the writing brush font is acquired as binary picture data.

In such a manner, the scratch and blur of the character by the writing brush are expressed and the witing brush font provided with scratch or blur expression is outputted. The method for acquiring the character skeleton is to utilize the Hilditch line thinning processing method in which a processing for making the font thin by deleting the outermost contour of the picture element constituting the font by one dot portion is repeated.  Further, the process for making the font thin by deleting one dot portion is counted as one time of line thinning processing, and number of times, at which each picture element constituting the character skeleton is positioned at the outermost block as a result of the line thinning processing, is recorded for every picture element, thereby determining the size of the dot pattern from the number of times.
